Evaluation of disease severity with quantitative chest CT in COVID-19 patients

New challenges for management of COVID-19 patients: Analysis of MDCT based “Automated pneumonia analysis program”

“…In contrast with our study they used an external software to calculate pneumonic scores which could make some delay to get results in a pandemic burden. They also reported in a similar way that the left lower lobe of lung was the most involved part in accordance with our study [ 24 ].…”

“…A similar approach was made by Furkan U. et al who assessed the severity of COVID-19 by quantitative and semiquantitative methods, but in a different way by calculating the involved lung volume with a formula including total lung from which the healthy lung part is subtracted and divided then by total lung volume to obtain a ratio [ 24 ]. In contrast with our study they used an external software to calculate pneumonic scores which could make some delay to get results in a pandemic burden.…”

COVID-19-associated pancytopenia and typhlitis

“…Pathological manifestations of typhlitis range from mucosal inflammation to transmural necrosis and may be further complicated by intestinal perforation or sepsis. Early diagnosis is of great importance because progression in typhlitis is associated with high morbidity and mortality [ [3] , [4] , [5] ]. Abdominal CT is beneficial in diagnosing typhlitis and can demonstrate circumferential bowel wall thickening and edema in the relevant bowel segments (usually in the cecum and ascending colon) and peri-intestinal fat-stranding.…”

“…The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19 (Coronavirus Disease 2019) and primarily affects the respiratory system [ 4 ]. However, it has been shown that it may affect many other systems, such as the hematopoietic system, and may cause lymphopenia, neutropenia, and rarely pancytopenia—only a few cases in the English literature report pancytopenia associated with COVID-19 [ 5 , 6 ].…”

“…It has a high morbidity and mortality rate [ 2 , 3 ]. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19 (Coronavirus Disease 2019) and primarily affects the respiratory system [ 4 ]. Still, it has been shown that it may affect other systems, such as the hematopoietic system, and may cause lymphopenia, neutropenia, and rarely pancytopenia [ 5 , 6 ].…”
